FIRE-RESISTING CURTAIN.

Specification of Letters Patent.

Patented Sept. 24, 1907.

Application flied April 1, 1905. senti No. 253,346.

To all whom it may concern:

Be it known that I, HERMAN E. VANC, a citizen of the United States,residing at Columbus, in the county of Franklin and State o Ohio, haveinvented certain new and useful Improvements in Fire-Resisting 'Curtainsand I do hereby declare the following to be a ull, clear, and eXactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This. invention relates to that class of flexible or rolling `lireresisting curtains which are made up of metallic slats or sectionshaving sheathings or coatings of nonmetallic re resisting or heatretarding material.

In some instances the resisting or retardent sheathings may be oi ratherbrittle or riable material and it will be important that the impact ofthe slats upon each other in such a way as to endanger the integrity oithe sheathing be prevented.

The object of the present invention therefore is to provide aconstruction slat and curtain in which contact between the sheathing ofa slat and another slat is in large measure or wholly prevented, and theinvention is embodied in the construction hereinafter described andclaimed, the invention not to be confined to the precise forms shown.

In the accompanying drawings in which is illustrated an embodiment ofthe inventionMFigure l is a perspective view oi a fraction of a curtainshowing also how the `slats can be connected; Fig. 2 is a sectional Viewtaken longitudinally through a slat as for example on the line x-x Fig.l. I

In the several views l designates the metallic portion of the slat. Thisportion can be'provided at its edges with hooks 20 rand shoulders 21,the latter standing across the mouthsfof the hooks after the mannerillustrated in the United States patent to W. R. Kinnear, No. 57 2,014dated November 24, 1896, said hooks adapt- 1 ing the slat to be joinedto other slats to form the curtain.

The body of the slat is provided with a series of ribs f or projectionslf. These ribs ln are shown transversely struck up or formed in thesheet metal of the slat, but they can be otherwise made. Between theribs is applied the sheathing or covering 2 which canv be of papier mch,asbestos cloth, or other heat and fire resisting material. The heat orlire resisting material 2 is applied to the slat only to such thicknessor depth as will permit the edges oi the ribs to lie substantially flushwith or project beyond the face oi the resisting material soy that whenone slat lies on another the contact and pressure of the former shall beborne by the ribs of the latter rather than by the fire resistingmaterial thereon. The resisting material on the slats is thus protectedfrom fracture or other injury when the curtain is rolled up.

What I claim and desire to secure by Letters Patent is:

1. A flexible fire resisting ycurtain embodying a plurality of hingedmetallic slats or sections provided with a sheathing or coating of heatresisting material, said slats or sections having projections extendingsubstantia11ythrough the outer surface of the coating or sheathing.

2. In a fire resisting curtain, a metallic slat provided with means forjoining it to other slats and having its body portion provided with asheathing of heat resisting material different from that of which thebody of the slat is formed and metallic projections extending from thebody of the slat substantially through the outer surface o f thesheathing.

3. In a fire resisting curtain, a metallic slat provided with means forjoining it to other slats and with projections beut up out of the bodyof the slat, and a sheathing,T of heat resisting material applied to thebody of the slat, said projections extending substantially through theouter surface of the sheathing.

n4. In a fire resisting curtain, a metallic slat provided with means forvjoining it to other slats, and with transverse metallic projections, asheathing of heat-resisting material on the slat between saidprojections, said projections extending` substantially through the outersurface of the sheathing.

5; In a Iire resisting curtain, a curved metallic slat provided withmeans'for joining it to other slats and with metallic projections, asheathingl of heat-resisting material on the slat between saidprojections, said projections extending from the body of the slatsubstantially through the outer surface of the sheathing.

In`testimony whereof I affix my signature, in presence of; twowitnesses.

HERMAN E. VANCE.
